Locally heavy rainfall is possible across central Louisiana late Wednesday night through Thursday afternoon. Several factors will combine to produce this potentially heavy rainfall event. The atmosphere contains deep, rich moisture and this will allow showers and thunderstorms to be efficient at producing rainfall. Upper level winds are light through a large depth of the atmosphere and this promotes slow-moving showers and thunderstorms. Finally, a significant short wave will excite the atmosphere and this will serve as the trigger for development. Event totals may exceed five inches.

Torrential downpours, on the order of 2-3 inches per hour, may occur. Prepare for the possibility of street flooding and very low visibilities if you have to drive through a heavy thunderstorm.

This wet pattern began Friday and rain chances remain above 50% through Saturday. "Normal" July conditions should return by Sunday. By then, the coverage of rain will become widely scattered and max temps will once again top 90 degrees.

I will prepare a summary of this wet spell based on data from the National Weather Service and our weather watchers network in a few days. Some locations have seen over 11 inches but others have measured less than one inch. That's testimony to the variability of convective rainfall.

Have a blessed day,

Tom Konvicka
